Well, first it is usually unnecessary to specify the
synonym filter both at index and query time, I'd apply
it only at query time to start, then perhaps switch
to index time, see the discussion at:

I think the point is that you need to expand synonyms at
index time but not at query time. In the field type definitions you
provided, the expansion happens both at index and query

Karsten,

"schools" and so i don't get results as required. It will initially split
"private schools" as "private" and "schools" and then try to match in
synonym filter. Th
Hi rajini,
multi-word synonyms like "private schools" normally make problems.
See e.g. Solr-1-4-Enterprise-Search-Server Page 56:
"For multi-word synonyms to work, the analysis must be applied at
index-time and with expansion so that both the original words and the
combined word get indexed. ..."
